  • Publication number: 20050118316
    Abstract: Maltitol crystals containing sugar crystals other than maltitol which have excellent solubility, almost no hygroscopicity, do not become bulky when they are stored or transported because they have a large bulk density, a small difference between packed bulk density and loose bulk density thereof and excellent flowability. The maltitol crystals containing sugar crystals other than maltitol have a loose bulk density of particles having a particle size of 20 to 50 mesh after grinding and classification of more than 0.750 g/cd and 0.850 g/cc or less.

  • Patent number: 6863737
    Abstract: A crystalline mixture solid containing maltitol having an oil absorptivity of 0.1 to 6.9 wt % and a bulk density of 0.60 to 0.75 g/cc when it is ground and classified to ensure that at least 70 wt % of the obtained particles should have a particle size of 16 to 50 mesh and a process for producing a crystalline mixture solid containing maltitol, comprising introducing air bubbles into a maltitol aqueous solution. According to this process, a crystalline mixture solid containing maltitol having high solubility and almost no moisture absorption is produced at a high work efficiency and a low cost in a short period of time.

  • Patent number: 6755914
    Abstract: A crystalline mixture solid composition comprising &agr;-D-glucopyranosyl-1,1-mannitol (GPM), &agr;-D-glucopyranosyl-1,6-sorbitol (GPS-6) and a small amount of &agr;-D-glucopyranosyl-1,1-sorbitol (GPS-1) and a production process therefor. The above crystalline mixture solid composition is produced by mixing a hydrophilic solvent with a solid composition or aqueous solution comprising 50 to 80 wt % of GPM, 1 to 50 wt % of GPS-6 and 0.01 to 20 wt % of GPS-1, separating solid matter from a liquid, and removing water and the solvent from the solid matter and can be obtained as a thin scale crystal.

  • Patent number: 5549919
    Abstract: The present invention relates to the preservation of foods, in which at least one kind of a natural antimicrobial agent selected from the group consisting of protamine, chitosan, and lysozyme to foods is added into the foods, and the foods obtained are stored in the presence of a deoxidizing agent under a substantially sealed condition. According to the present invention, the deterioration of foods by microbes, yeasts and the like which has not been sufficiently prevented by the use of conventional natural antimicrobial agents can be effectively prevented.

  • Patent number: 5304388
    Abstract: Disclosure is a method for converting maltitol into crystalline powder by very simple procedures and in short time. To an aqueous solution of maltitol with 1-15% by weight of moisture content, seed crystals of maltitol are added and a shearing force is applied continuously at a temperature lower than the melting point of the seed crystals, thus obtaining a powdery crystalline maltitol.
